The [u?] diphthong. This is another diphthong that is sometimes left out of sources as it is always followed by the consonant R, and these sources consider the schwa sound, the second half of this diphthong, to not actually be its own sound.

The first sound: uh as in pull is how it is written. However in practice, I find it to have some of the oo as in boo mixed in. luh-uh-uh-uh as in lure. In slow motion: ooooo uuuuuuuhhhh rrrr. So the sound goes from the uh or oo sound, where the lips are more rounded, to the schwa, where the mouth is very relaxed and the tongue is very relaxed, to the rr, rr, where the lips come in a little bit, the then push out a little bit, and the throat closes a tiny bit here to make the sound come from uhh.

[u?]是一個(gè)雙元音，有些研究發(fā)音的材料中認(rèn)為這個(gè)音是[u]和R音的組合，當(dāng)中的[?]音并不發(fā)聲。

第一個(gè)音，雖然寫(xiě)做[u]（pull一詞中的[u]音），但是念的時(shí)候卻混合了一些[?]的成分（boo一詞中的[?]音）。我們來(lái)試著念一下lure一詞中的[u?]音，用慢動(dòng)作來(lái)念就是：ooooo uuuuuuuhhhh rrrr。也就是說(shuō)，[u?]這個(gè)音是從唇形較圓[u]或者說(shuō)[?]音，到嘴型和舌頭都十分放松的[?]音，再到嘴唇略微向中間聚攏并向前突出，而喉嚨處略微縮緊的R音。
